It might not even be extending her unbeaten streak to 14 races. Or becoming the first distaffer to win the Classic.
It might be that after coming from last to win by 1 length, she seemed to be looking around for more to do.
Winning jockey Mike Smith said he had to work to get Zenyatta to concentrate enough to run down Gio Ponti in deep stretch. But even then, he said, "she still went, believe it or not, well within herself. She was pricking her ears and galloped out. She didn't even take a breath after the race was over. It's just incredible."
Sadly, that's it. For Zenyatta, there are no more hills to climb and no more rivals to circle on the turn with the trademark move that defeated all comers.
The only battle left is for Horse of the Year honors against Rachel Alexandra -- the 3-year-old filly who dominated East Coast racing this year.
Rachel Alexandra skipped the Breeders' Cup because majority owner Jess Jackson doesn't like the Santa Anita artificial surface -- and because it was widely assumed his filly had already locked up Horse of the Year honors.
"I wish they would have brought her here to prove to the racing world what Zenyatta is really about," Smith said. "I'm not going to say I'd have beaten her, because that's one person's opinion. I'd have given anything to run against her."
Among those they did run against, Arlington Million winner Gio Ponte finished second, European star Twice Over was third, Belmont Stakes winner Summer Bird finished fourth and Kentucky Derby winner Mine That Bird got home ninth.
Zenyatta's owner, Jerry Moss, said, "She's our Horse of the Year."
In other results from the Breeders' Cup World Championship program:
Conduit made it two straight wins in the $3 million Emirates Airline Turf, rallying nicely from last to win by 1 1/2 lengths over runaway pace-setter Presious Passion. European filly Dar Re Mi finished third. Sir Michael Stoute trained Conduit and fourth-place finisher Spanish Moon. "It's always a big day for the world championship," Sir Michael said. Winning jockey Ryan Moore said he wasn't worried about catching Presious Passion despite giving up the big lead. "I knew I was going to get there," he said.
Pounced came from Europe to win the $1 million Juvenile Turf by 3/4 length over Bridgetown. Pounced, a Rahy colt, went off as the favorite and was the second straight winner of this race for trainer John Gosden, who scored last year with Donativum. He likely will be a contender in the English classics next spring. Nat Rothschild, representing the owners, said they "don't think about the next step. This is a great achievement for us."
California Flag and Gotta Have Her carried the local colors to a 1-2 finish in the $1 million Turf Sprint with California Flag leading from gate to wire and Gotta Have Her running from far back. Cannonball, an American who raced at Ascot this summer, finished third. Winning rider Joe Talamo is only 19 years old. "I'm humbled by the experience," he said. "I really am."
Dancing in Silks led a parade of upsetters in the $2 million Sentient Jet Sprint, winning by a nose in a four-horse blanket finish. With Crown of Thorns and Cost of Freedom second and third, the $1 trifecta returned $2,145.90. The favorite, Zensational, got off a step slow and finished fifth. Second favorite Gayego got home fourth. "My horse always has his head up so I was hoping that would help at the finish," said winning rider Joel Rosario.
Vale of York, gave Godolphin Stable a ray of sunshine in an otherwise somewhat disappointing Breeders' Cup as the longshot son of Invincible Spirit rallied between horses to win the $2 million Grey Goose Juvenile by a head over favorite Lookin at Lucky. Godolphin racing manager Simon Crisford said the victory moves Vale of York to the No. 1 spot in Godolphin's 2010 Kentucky Derby prospect list, though he will winter in Dubai.
Goldikova reprised her 2008 victory in the $2 million mile, rallying this time from the outside post position and the back of the pack to score by 1/2 length over Courageous Cat. Her back-to-back wins give trainer Freddie Head four wins in the event. He scored back-to-back victories riding Miesque in 1987 and 1988. "We haven't discussed her future," Head said of his 4-year-old. "Maybe we'll come back and try for three" when the Breeders' Cup returns to Churchill Downs in 2010.
Furthest Land upset the $1 million Dirt Mile, sticking close to the lead and getting clear at the end to beat late-running Ready's Echo by 3/4 length, keying a $1 trifecta return of $2,933.40. Midshipman, who won last year's Juvenile, finished third after leading most of the way. Furthest Land finished fourth in the Claiming Crown Jewel this summer, then won the Kentucky Cup Classic at Turfway Park en route to the Breeders' Cup. He earned $540,000 Saturday. Owner Ken Ramsey said he's thinking about the Dubai World Cup.
On Friday's card:
European runner Man of Iron got the upset-filled Championships off to a minor surprise by winning the $500,000 Marathon by a nose over 9-year-old Cloudy's Knight. Another European, Mastery, was the favorite and finished third. Trainer Aidan O'Brien said jockey John Murtagh told him he would "take his time because that's the way he likes to be ridden. That's what he did." The winner is a 4-year-old Giant's Causeway colt.
Tapitsfly got past pace-setting Rose Catherine in the final jumps to win the $1 million Juvenile Fillies Turf by 1/2 length with House of Grace third. Tapitsfly, raced in Kentucky and New York, got her third win in seven starts. "She's a little fighter, I'll tell you that," said winning jockey Robby Albarado.
She Be Wild got through an opening along the rail at the top of the stretch in the $2 million Grey Goose Juvenile Fillies and went on to win by 3/4 length over Beautician. Blind Luck was third as the favorite. She Be Wild, an Offlee Wild filly who campaigned in Chicago and Kentucky, now has four wins and a second from five career starts. "I got a perfect trip," said winning jockey Julien Leparoux. "I was on the rail all the way."
Midday got to the lead with a furlong left in the $2 million Emirates Airline Filly & Mare Turf and kicked home first, 1 length better than Pure Clan. Forever Together, winner of last year's running, finished third. Midday, a 3-year-old, British-bred filly, finished third in the Prix de l'Opera at Longchamp a month earlier. She also was third in the Irish Oaks and second in the English Oaks this summer. "I saw lots of rails all the way around," said jockey Thomas Queally. "It was a dream run."
Informed Decision pressed the pace in the $1 million Sentient Jet Filly & Mare Sprint, got the lead in the stretch and held on to win by 1 1/4 lengths over defending champion and favorite Ventura. Free Flying Soul made the early pace and held on for third. Informed Decision has lost only once in seven starts this year -- that on a sloppy track at Belmont Park. Winning trainer Jonathan Sheppard said he knew Ventura would be coming late. "But our filly galloped so hard to the line, she wasn't going to catch us."
He said Informed Decision, a 4-year-old, will stay in training next year.
Life Is Sweet came from last of eight to upset the $2 million Ladies Classic, winning by 2 1/2 lengths over Mushka with Music Note third and the favorite, Careless Jewel, last after setting the pace. Life Is Sweet, a 4-year-old Storm Cat filly, had been chasing Zenyatta in most of her races this summer and found the going a bit easier without that rival. "When you have some tough races like she did, it will take something out of you," said winning jockey Garrett Gomez. "I'm glad they were able to get her confidence back."

With Channing Hill up, Expansion ran the 1 3/8 miles on firm turf in 2:18.93.
Buddy's Saint stalked the pace in Saturday's $150,000 Nashua Stakes for 2-year-olds, then hit the afterburners in the stretch, running away from the competition to win by 12 lengths.
